Note any deviations between the instrument and the pressure
standard and consider traceability (accuracy to a National Standard).
If, after a calibration check, the results exceed the tolerance in the
specification (or other suitable performance standard), carry out a
calibration adjustment.
5.3
CALIBRATION ADJUSTMENTS
If the instrument is operating correctly, only zero and full-scale
calibration will vary. Any excessive non-linearity or temperature
effects indicate a fault. The instrument should be returned to a
qualified service agent.
5.4
BEFORE STARTING
Use only original parts supplied by the manufacturer. To do an
accurate calibration, use the following:
•
Calibration equipment specified in
Table 5-1
.
•
Stable temperature environment: 21 ± 1°C (70 ± 2°F).
Before starting a calibration procedure, it is recommended leaving the
equipment in the calibration environment for a minimum of two
hours.
